Abstract	Danas je elektropećni postupak dobivanja čelika jedan od najzastupljenijih u svijetu stoga je bitno daljnje unapređenje procesa s ciljem što bolje učinkovitosti te sa time i smanjenjem troškova i utjecaja na okoliš. Jedan od velikih faktora u ekološkom i financijskom smislu je remont vatrostalnog dijela peći gdje nastaju velike količine istrošenog vatrostalnog materijala. Na vatrostalni obzid peći utječu različiti čimbenici a jedan od najvažnijih je troska. Troska se u osnovi dobiva dodatkom vapna u uložak, a sastav vapna uvelike utječe na proces proizvodnje čelika. Koriste se vapna na osnovi kalcija (CaO) i vapna na osnovi magnezija (MgO). U ovom radu će biti istražen utjecaj dodatka magnezitnog vapna u elektrolučnu peć na procese odsumporavanja i odfosforavanjate na trošenje vatrostalnog obzida uz osvrt i na sami remont peći.
Abstract (english)	Today, the electric arc furnace process of steel production is one of the most common in the world, so it is important to further improve the process with the aim of better efficiency and thus reduce costs and environmental impact. One of the major factors in environmental and financial terms is the overhaul of the refractory part of the furnace where large amounts of spent refractory material are generated. The life of refractory wall of the furnace is affected by various factors and one of the most important is slag. The slag is basically obtained by adding lime to the bucket with cartridge, and the composition of the lime greatly influences the steel production process. Calcium-based lime (CaO) and magnesium-based lime (MgO) are used. In this paper, the influence of the addition of magnesite lime to the electric arc furnace on the processes of desulphurization and phosphorization and on the wear of the refractory wall with a review on the furnace overhaul itself will be investigated.
